Abstract
digital ambition into concrete, process-anchored objectives, which makes prioritization by process value enforceable rather than aspirational. The middle stages protect momentum through visible early wins in high-impact areas such as reporting automation, and these wins build the acceptance that the barrier analysis identified as critical. Table 4. Implementation roadmap based on Kotter's change management model. The closing stages anchor new routines in roles, job profiles, and governance, so that gains achieved in pilots survive once attention moves on. Read this way, the model operationalizes the central finding that digital benefits rest on stable data, processes, and competencies, not on technology alone (Sievers & Dulgeridis, 2026). 5.5 Depth and interplay of technological effects Beyond the question of where the technologies are deployed, the review shows that they act at different depths within each process. Robotic Process Automation and Business Intelligence operate mainly at the level of data integration, standardization, and the automation of execution, which gives them a structural and operational character. Predictive Analytics and Artificial Intelligence reach further into analytical and decision-oriented tasks, because their contribution lies in forecasting, pattern recognition, and the interpretation of complex data. The same technology can therefore act at different depths in different processes. Artificial Intelligence, for example, automates the classification of cost data in cost accounting, yet it supports anticipatory analysis and commentary in forecasting and reporting. This depth perspective explains why coverage alone is a weak measure of digital maturity, since a process can show many tool mentions while the underlying effect stays shallow (Sievers & Dulgeridis, 2026). The decisive implication is that holistic value arises from the coordinated interplay of structural, operational, and analytical contributions rather than from any single technology. Business Intelligence and data integration establish the foundation, Robotic Process Automation stabilizes and scales execution, and Predictive Analytics and Artificial Intelligence build the anticipatory and interpretive layer above them. Where this interplay is missing, predictive and AI-based applications stay limited, because they depend on consistent data and stable processes, and the structural technologies in turn realize their full steering value only when their outputs feed analytical and decision-oriented use. Digital maturity must therefore be assessed at the level of integrated process support, not at the level of individual tools (Sievers & Dulgeridis, 2026). 6 Conclusions, Limitations and Further Research: Beyond Digital Adoption: The study examined how BI, PA, AI, and RPA affect management accounting processes and professional roles, based on a systematic review of 50 sources. The technologies are deployed in process-specific ways, with AI and PA strongest in planning, budgeting, and forecasting, BI and RPA strongest in reporting and standardized routines, a hybrid profile in cost, activity, and profit accounting, and a selective profile in investment controlling. Their benefits cluster in automation, transparency, and predictive capability, and they materialize only under stable data, system, and competency conditions. The professional focus shifts toward analytical advisory and business partnering, while the independence of the control function comes under pressure. The scientific contribution is the process-based orientation framework that integrates technologies, benefits, barriers, and competencies, and the practical contribution is a process-based, actor-specific logic for prioritizing initiatives and developing competencies (Sievers & Dulgeridis, 2026). Several limitations apply. The study rests exclusively on secondary sources, so statements about real implementations remain literature-based tendency statements rather than measured adoption rates. A publication bias cannot be excluded, because studies that emphasize benefits tend to be more visible than reports of disappointed expectations. The temporal restriction to publications from 2020 keeps the analysis current but excludes longer-term studies, and findings on rapidly developing AI applications can lose currency quickly. The restriction to German and English sources further bounds the evidence base and may omit insights from other language areas and economic regions, including technologically advanced markets. Because the analysis proceeds along broad process groups, it also abstracts from process-specific detail that a narrower focus would reveal, and the evidence base for investment controlling is particularly thin, with only nine sources, so the findings for that field are exploratory rather than robust.
